Abstract

Automatic Transfer Switch (ATS) adalah suatu piranti sistem listrik yang berfungsi untuk mengatur proses pemindahan sumber listrik dari sumber listrik yang satu (utama) ke sumber listrik yang lain (cadangan) secara bergantian yang dilakukan secara otomatis. Dengan menggunakan piranti ini, maka tidak diperlukan lagi menggunakan saklar Change Over Switch (COS) yang dilakukan secara manual dalam proses pengalihan antara sumber listrik utama ke sumber listrik cadangan. Pada penelitian ini dibuat suatu desain sistem ATS yang dapat melakukan proses pengalihan perpindahan dua sumber listrik yang aman dan efektif secara sekuensial sesuai dengan proses kerja yang dikendalikan oleh pengontrol secara otomatis berdasarkan besarnya pemakaian daya listrik. Untuk mendapat ketepatan dalam pengalihan sumber listrik utama ke sumber listrik cadangan diterapkan atau digunakan mode switching dengan system pengendali interlock. Dengan menggunakan ATS berbasis mikrokontroler ESP8266 dapat menyelesaikan permasalahan pengalihan dua sumber listrik yang aman dan efektif, serta dapat dimonitor melalui antarmuka smartphone.

Abstract

This article compares the voltage drop on Lead-acid and Lithium-ion batteries used as an energy source for electric scooters. An experiment was conducted with five electric scooter users weighing 60.25 Kg, 70.60 Kg, 83.20 Kg, 95.40 Kg, and 103.75 kg to obtain data on voltage drop. Each user of this electric scooter carried out three experiments by circling about 1.07 Km at the Politeknik Negeri Bali area. This study proves that the voltage drop on the Lead-acid and Lithium-Ion batteries has a linear relationship to the weight of an electric scooter user with a 36V 400-watt BLDC motor load. The linear equation has an intercept value of -1.36766 and a slope value of 0.04791 for the Lead-acid battery. In contrast, the linear equation has an intercept value of -2.47064 and a slope value of 0.05417 for Lithium ion batteries. The average voltage drop across lead acid is 25% higher than that across Lithium-ion

Abstract

An electric vehicle uses increasing in Indonesia. Airport services are also advancing the development of electric cars on Baggage Towing Tractors (BTT). BTT is used to attract aircraft baggage to the terminal baggage queue. BTT uses an electric engine as a driving force and an 80V battery as a voltage source. If the BTT battery is not managed correctly, then it is an effect on the battery life. This battery is prone to over-voltage, under-voltage, and over-heat. The project is necessary to develop a system that makes it easier for users to monitor battery performance and technicians during maintenance. The concept of this system is based on an android application. This application will provide real-time information about battery voltage, temperature, and humidity through Firebase Database. The data received by sensors is sent to the database via a microcontroller, which is connected to a Wi-Fi network. The android application will access the database and display data in real-time by ignoring previous data. This system is designed for users to determine the condition of the BTT battery that will be used. The system was tested to evaluate measurement accuracy and speed of updating data. From the test result, the level of accuracy system is around 97%, and it’s rated as working optimally.

Abstract

Fire & gas safety control is a control system to secure a room / building from the danger of gas leakage or fire. In the current era, the development of building architecture requires us to always innovate in maintaining the safety of the occupants or the building itself. This research makes an Advance Fire & Gas Safety Control tool which aims to minimize false alarms, especially regarding steam. Smoke and steam can be distinguished by the level of humidity. Smoke, which is particulate matter, has a very low humidity level, while steam has a very high humidity level. This research implements NodeMCU ESP8266, MQ-2 Sensor, DHT11 Sensor, Fire Sensor, Buzzer, Firebase and Kodular, to detect fires, steam and gas leaks.

Abstract

The government's recommendation to wear masks daily is very important to avoid the Covid-19. This article analyzes the use of the ESP32 Cam as a mask detector, where proper use must cover the nose and mouth. The captured images can be retrieved and executed by a program created using Python. The OpenCV library is used to access the camera, while the TensorFlow library with training files in the datasheet performs mask detection. The experimental results of detecting masks in bright conditions show the fastest time is 1 second with an ideal distance of 1m and a maximum distance of 2.5m. On the other hand, in dark conditions, the fastest time is 2 seconds with an ideal distance of 1m and a maximum distance of 1.5m.

Abstract

Mikrokontroler merupakan bagian inti dari proyek kontrol otomatis. Pemilihan mikrokontroler sangat berpengaruh terhadap hasil pengolahan data pada sistem. Atas dasar pemikiran tersebut maka dilakukan sebuah penelitian yang bertujuan untuk menemukan mikrokontroler dengan kemampuan pengolahan data yang baik. Dalam penelitian ini menggunakan mikrokontroler Arduino Uno dan mikrokontroler ESP32. Di mana kedua mikrokontroler tersebut memiliki spesifikasi yang berbeda. Data yang digunakan berupa nilai tegangan dan arus yang diperoleh dari sensor tegangan ZMPT101B dan sensor arus ACS712. Pengujian yang dilakukan menghasilkan nilai rata-rata error tegangan sebesar 0,387649 persen dan arus 3,095044 persen untuk mikrokontroler Arduino Uno. Sedangkan untuk mikrokontroler ESP32 menghasilkan rata-rata nilai error tegangan sebesar 0,312182825 persen dan arus sebesar 0,194657573 persen.
